Be it known that I, CARLETON ELLIS, a

' removers and is comparatively free from objection on account of itsodor. The commercial pentachlorethylene, or pentachlorethane as it issometimes called for instance, has-an odor similar to that ofturpentine. Trichlorethylene and both pentachlorethane andtetrachlorethylene are also desirable chlorinated solvents and may beused in connection with the alcoholic or other loos ening or otherfinish solvent material and preferably incorporated with suitablethickeners as well as preservative or antacid material if desired. Insome cases, such as in steamboat work, where an especiallynoninflammable remover is desired cresylic acid or other phenolicmaterial may be incorporated in suitable proportions which will.

also have a desirable antiseptic action. An illustrative remover maycomprise the following ingredients: pentachlorethane 10 gallons,tetrachlorethylene 40 gallons, ethyl alcohol 50 gallons, methyl alcohol2% gallons, celluloid pounds, ceresin wax 25 pounds, dry soap 10 pounds,sodium benzoate 5 pounds. This remover may preferably be prepared bydissolving the celluloid in the alcoholic solvent'material in astrongmixing apparatus in which the solvent action is energetically promoted.The chlorinated solvents may then be added very gradually in order toavoid precipitating the celluloid and an excessive quantity of thechlorinated solvents should be avoided for a similar reason. The mixturemay then be heated to 40 or degrees C. and the wax added preferably in amelted condition and then the sodium benzoate and dry soap orSpecification of Letters Patent.

other antacid material preferably in finely powdered conditionthoroughly incorporated and the mixture cooled after filtering when m aheated condition if desired, although, of course, it is understood thatthe ingredients may be incorporated in other ways. Such antacid orpalliative material of course prevents or neutralizes any slight acidtendency in removers containing chlorinated solvents for instance as isknown in the art. This formula gives a remover of syrupy or smooth pastyconsistency desirable for general purposes, although of course theincorporation of more of the ordinary laundry soap or various potash orothersoaps 1f desired gives a greater consistency sothat by the use oflarger quantities a stifl or jellylike remover may be'secured, or byusing less of thestlfi'ening material the remover may be made morefluent so asto approach the fluidity of the solvents themselves. The

soap is highly desirable in this connection in preventing the celluloseor celluloid from forming a hard adherent film in case the removershould be allowed to become entirely dry on the wood to which it isapplied, or on brushes or other articles. Other suitable illustrativeremovers may be prepared according to the following formulas:
